There was U2, who performed their “Ordinary Love” from the movie Mandela: Long Walk to Freedom,Karen O of the Yeah Yeah Yeahs performed “The Moon Song” from Her, accompanied by Ezra Koenig of Vampire Weekend on acoustic guitar, and Pharrell got delirious with his performance of “Happy” accompanied by a group of dancers and a high school chorus.
